Searches for the exclusive decays of Higgs and $Z$ bosons into a vector quarkonium state and a photon are performed in the $\\mu^+\\mu^- \\gamma$ final state with a proton--proton collision data sample corresponding to an integrated luminosity of $139$ fb$^{-1}$ collected at $\\sqrt{s}=13$ TeV with the ATLAS detector at the CERN Large Hadron Collider. The observed data are compatible with the expected backgrounds. The 95% confidence-level upper limits on the branching fractions of the Higgs boson decays into $J/\\psi \\gamma$, $\\psi(2S) \\gamma$, and $\\Upsilon(1S,2S,3S) \\gamma$ are found to be $2.0\\times10^{-4}$, $10.5\\times10^{-4}$, and $(2.5,4.2,3.4)\\times10^{-4}$, respectively, assuming Standard Model production of the Higgs boson. The corresponding 95% CL upper limits on the branching fractions of the $Z$ boson decays are $1.2\\times10^{-6}$, $2.4\\times10^{-6}$, and $(1.1,1.3,2.4)\\times10^{-6}$. An observed 95% CL interval of $(-133,175)$ is obtained for the $\\kappa_c/\\kappa_\\gamma$ ratio of Higgs boson coupling modifiers, and a 95% CL interval of $(-37,40)$ is obtained for $\\kappa_b/\\kappa_\\gamma$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.132657.v2/t1","@type":"Dataset","description":"Numbers of observed and expected background events for the $m_{\\mu^+\\mu^-\\gamma}$ ranges of interest.
